IMPROVEMENT IN BATTEN RQOFS OR WALLS.

Specication forming part of Letters Patent No. 184,576, dated November21, 1876; application le May 13, 1876.

To all whom it may concern:

Be it known that I, RANDALL BENTLEY, of the town of Owen Sound, in thecounty of Gray, in the Province of Ontario, in the Dominion of Canada,have invented certain new and useful Improvements in the Constructionot' Roofs and Walls for Buildings; and I do declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, and tothe letters of reference markedthereon.

The nature of my invention relates to a mode of forming roofs and wallsfrom troughs and battens sztwed from solid timber, as will behereinafter more particularly described.

In the annexed drawings, making part of this specification, Figure 1represents a perspective view ot' a portion of a-roof' or wall, and Fig.2 an end View of the timber from Which the parts forming the same aresawed.

In the gures, A represents a block of timber of any suitable length.From this block, and lengthwise of it, are sawed the two troughs B and Uand the battens D. E represents a scantling or joist, upon which theroot' is placed. These scantlings are cut with joining V-shaped openingsuponl an angle with the larger troughs B B. The troughs B B are laidupon these joists in their openings, with their vertices downward andtheir upper edges adjoining. The troughs C C are then placed over thejoints of troughs B B, with their vertices upward, for'the purpose ofbreaking the joints. The battens D D are then placed, as seen, betweenthe troughs C U and secured, their vertices being downward, so as tocontine the lower edges ot' the troughs C C, to prevent their bending orwarping. When these troughs B and Gand the battens D are secured inposition upon-thejoist as constructed,

a rootl or wall is formed which is impervious
